3 gang 1 way light switch
This format of light switch has three discreet switches on a single face plate. Basically this is three Single gang 1 way switches on a single face plate.
The only place you would use such a beast is if you had three lights (or sets of lights) in a single room each controlled by one of the single switches. This arrangement is not common, you are most likely to find a 3 gang 2 way switch used (this will do the same job but you will have spare L2 terminals on each gang that you would not need to use).
Switch mechanism
Each of the gangs (or switches) above in Fig 2 (of which there are three) work like this: when the switch is ‘on’ the COM and L1 terminals are connected together. When ‘off’ the COM is connected to nothing.
There are no connections between the two gangs in Fig 2. Each gang is a single discreet switch.

This format of light switch has three discreet switches on a single face plate. Basically this is three Single gang 2 way switches on a single face plate.
Switch mechanism
Each of the gangs (or switches) above in Fig 2 (of which there are three) work like this (Fig 3): In position 1 (when the switch is down or ‘on’), COM and L1 are connected together (just like the one way switch). In position 2 (when the switch is up or ‘off’), COM and L2 are connected together.
There are no connections between the three gangs in Fig 2. Each gang is a single discreet switch.

The 3 gang intermediate light switch is used where three or more switches control one light and used in conjunction with two two way light switches to achieve this. It is effectively three single gang intermediate switches on one face plate.
Switch mechanism
Each of the gangs (or switches) above in Fig 2 (of which there are three) work like this (Fig 3): There are four terminals, usually L1, L1 and L2, L2. In one position, L1 and L2 are connected in pairs. In the other position, alternate pairs are connected.
